“…14 C is produced in the upper atmosphere from cosmic ray spallation and is then rapidly oxidized to 14 CO 2 , distributed throughout the biosphere, and ultimately, over time, incorporated in the organic and carbonate components of soils and sediments. Natural radiocarbon can be used to date PyC from ∼50,000 yr ago to ∼1960 (e.g., Masiello & Druffel 1998, Bird 2013. Atmospheric nuclear testing in the mid-twentieth century introduced a pulse of 14 C into the atmosphere, which is progressively also being taken up into the biosphere and provides a tracer for modern carbon in the environment.…”

Pyrogenic carbon (PyC; includes soot, char, black carbon, and biochar) is produced by the incomplete combustion of organic matter accompanying biomass burning and fossil fuel consumption. PyC is pervasive in the environment, distributed throughout the atmosphere as well as soils, sediments, and water in both the marine and terrestrial environment. The physicochemical characteristics of PyC are complex and highly variable, dependent on the organic precursor and the conditions of formation. A component of PyC is highly recalcitrant and persists in the environment for millennia. However, it is now clear that a significant proportion of PyC undergoes transformation, translocation, and remineralization by a range of biotic and abiotic processes on comparatively short timescales. Here we synthesize current knowledge of the production, stocks, and fluxes of PyC as well as the physical and chemical processes through which it interacts as a dynamic component of the global carbon cycle.

“…Lastly, samples were slowly dried at room conditions, packed and submitted to the 14 C dating to Isotoptech Zrt. laboratory in Debrecen (Hungary), where they were further purified by standard laboratory protocols (Bird et al 1999(Bird et al , 2003ABOX pretreatment;Bird 2013). The AMS measurements were performed in Mini Carbon Dating System MICADAS.…”

Radiocarbon Dating of Grass-Tempered Ceramic Reveals the Earliest Pottery From Slovakia Predates the Arrival of Farming

et al. 2023

In the absence of wood, bone, and other organics, one possible candidate for determining the age of a site is the radiocarbon (14C) dating of pottery. In central Europe during the Early Neolithic, pottery was ubiquitous and contained substantial quantities of organic temper. However, attempts at the direct dating of organic inclusions raises a lot of methodological issues, especially when several sources of carbon contribute to the resulting radiocarbon age. Hence an alternative approach to dating of the early pottery is necessary. Here, we present a novel method of bulk separation of organic content from the grass-tempered pottery from Santovka (Slovakia). The procedure is based on the consecutive application of three inorganic acids, dissolving clay, silica content, and low molecular or mobile fractions to separate organic inclusions added to the pottery matrix during the formation of vessels. Radiocarbon dates obtained with this method are coherent and produce the shortest time span compared to other pretreatment methods presented in this study. The paired dates of grass-tempered pots with the 14C age of lipids extracted from the same pots point to a difference of 400–600 14C yr, however they are in line with the site’s chronostratigraphic Bayesian model. Grass-tempered pottery from Santovka (Slovakia) is dated to the first half of the 6th millennium cal BC, making it the earliest pottery north of the Danube. It seems feasible that ceramic containers from Santovka were produced by hunter-gatherers, and pottery predated the arrival of farming in the Carpathian region by a couple of centuries.
